WILLIAM M. HOLLOWAY, OF CHICAGO, ILLINOIS.

SOLDERING-MACI-IINE.

To all whom it may concern:

Be it known that I, l/VILLIAM M. HoLLowar, a. citizen of the UnitedStates, and a resident of the city of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inSoldering-Machines; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

This invention relates to improvements in soldering machines and isshown more particularly as adapted for soldering bail ears or lugs onpail blanks.

In the construction of sheet metal or tin pails such as are usedextensively for lard pails and for many other purposes, a bail ear orlug is soldered on opposite sides of the pail near the top to receivethe bent wire bail of the pail. I-Ieretofore the securing of said lugsupon the pailor upon the blank has been a comparatively slow operationand necessarily more expensive than is desirable.

The object of this invention is to aiford an exceedingly cheap, simpleand positively operating machine whereby the pail blanks of suitablesize are fed flat into the machine, and the bail lugs secured in placeby the use of heat applied from below or the opposite side of the blank,the blank at the point opposite the lug or ear being subjected to a coldblast after the lug is attached and before delivery from the machine.

It is also an object of the invention to afford means for adjusting themachine for blanks for different sizes of pails and also for differentheights or sizes of bail lugs and to so construct the machine that theparts thereof in any manner subjected to heat, are open to theatmosphere to permit of rapid radiation.

The invent-ion embraces many novel features and consists in the mattershereinafter described and more fully pointed out and defined in theappended claims.

In the drawings: Figure 1 is an end elevation partly broken of a machineembodying my invention. Fig. 2 is a top plan View thereof. Fig. 3 is acentral vertical section of the machine taken longitudinally of theshaft and showing the shaft in elevation. Fig. 4 is a section on line 4%of Fig. 2.

Specification of Letters Patent.

Application filed June 15, 1908.

Patented Nov. 23, 1909. Serial No. 438,461.

Fig. 5 is an enlarged fragmentary detail taken in section, andillustrating the construction of the heating plates and burner. Fig. 6is a similar fragmentary view taken in elevation and showing the coldblast pipes. Fig. 7 is an enlarged fragmentary section of the cam andring. Fig. 8 is a detailed face view of the driving gear for the Genevagear.

As shown in the drawings: Said machine comprises a frame consisting ofend members A, which may be of cast metal or constructed of any suitablematerial, and are rigidly connected on opposite sides longitudinallythereof by side bars aa, which serve to stiffen the frame and afford atable upon which at each end are bolted uprights a a a upon which themain shaft B, is journaled. As shown, said frame members may also beconstructed of cast metal of suitable shape to afford a support for thedriving gears as Well as said shaft, as shown in Fig. 1, each of saidend frame members o a*, on the driving end of the machine being extendedrearwardly and approximately horizontally from the shaft B, for thatpurpose.

As shown, a shaft B, is journaled at the top of the frame members a aparallel with the shaft B, and secured in the outer end of the shaft isa driving pulley Z), adapted to be engaged by a belt driven from anysource of power. Also secured on said shaft, is a pinion b, which mesheswith a gear 6 on a shaft B parallel with and at the rear of the shaft B.Also secured on said shaft B is a pinion b which meshes with a gear 6*,rotative on the shaft B, and provided, as shown in Figs. 2 and 5, on itsinner face with a pin 6 adapted to engage in the radial slots of aGeneva gear 6, secured on the main shaft B. Said Geneva gear, as shown,is provided with a number of radial slots corresponding with the numberof intermittent movements of the shaft B, in each revolution thereof andintegrally secured 011 said gear o is a segment 6 adapted to engage inthe concave seats in the periphery of the Geneva gear between the slotsto hold the shaft B, rigidly between the intervals of movement thereof.

Feathered on the shaft B, are carrying wheels CG, of equal size, and, asshown, provided on the periphery with a number of flat facescorresponding with the number of slots in the Geneva gear. In thepresent machine, ten of such flat faces are provided, which, as shown,are directed obliquely with the radius of the wheel passing through thecenter thereof, thus providing at the rear side of each of said flatfaces, a radial, outwardly directed, ratchet-like shoulder 0. The rim orface of each wheel, as shown, is comparatively broad, and at the inneredge said rim is integrally connected with the web on which is securedan integral hub 0 adapted to be held from rotation on the shaft by meansof a feather c and held from longitudinal movement in adjusted positionon the shaft by means of a set screw 0 or any other suitable equivalenttherefor.

Each of the flat rim faces of the wheel is cut, as shown in Figs. 1, 3and 5, to afiord a comparatively large opening therethrough adapted tobe covered by a relatively thin plate of sheet steel or other suitablemetal 0, adapted to quickly radiate heat, and provided with a circularaperture therethrough.

Pivotally secured on each of the shoulders c, is a clamping arm D, whichextends centrally over said plate 0 and is provided on its under sidewith a seat adapted to receive the ear or lug therein, as shown indotted lines in Fig. 2, and as shown, a lever arm (Z, rigidly secured onsaid clamping arm at the end thereof depends from the pivot pin d, andis provided at its lower end with a roller (Z adapted to engage theactuating cams whereby said clamping jaws are actuated. As shown, saidcams indicated by DD are adj ustably secured upon a ring (Z concentricwith the shaft B. Said ring is held from rotation on the shaft by meansof a bar (1*, bolted to the ring (Z and also adjustably secured at itslower end on a longitudinal bar (Z bolted. to the frame. The cams, asshown, are provided with parallel, longitudinal slots adapted to receivetherein bolts (Z which rigidly engage the cam to the ring but whichpermit the same to be adjusted outwardly or inwardly by releasing thebolts. As shown, the cam D, projects forwardly from the shaft B, intoposition to be engaged by the rolls 6Z on the end of the clamping levers(Z, to throw the clamping jaw outwardly from clamping position and tohold the same outwardly while inserting the blank and the ear lugs inplace. The cam D extends obliquely downwardly and rearwardly from theshaft in position for engagement by the rolls (P, on the clamping leversto throw the clamping jaw outwardly from clamping position to releasethe blank after the operation is completed. As shown also, the Web ofeach of said carrying wheels is provided in advance of each of theclamping levers with a lug (Z through which extends a push pin (Z whichbears on the forward side of the clamping lever and a spring 0Z isprovided on said push pin, which acts normally to hold said clamping jawin clamping relation, as shown in Fig. 4. As shown, the two carryingwheels are identical in construction in. all respects and arranged withthe webs on the inner sides thereof and are entirely open on the outersides or ends of the machine.

Extending upwardly at the front of the machine is the fuel supply pipeE, which extends through a suitable adjustable clamp on the frame bar a,and extends into the open end of the carrying wheel C,'and curvingupwardly over the shaft is provided, as shown, with three branch pipese-e -e each provided with a suitable burner nozzle 6 inclosed in asomewhat conical tube 6 adapted to direct the frame through the aperturein the plate 0 when the carrying wheels are at rest, said branches beingso arranged that the burners act upon three of the adjacent apertures inthe carrying wheel at the same time whenever said wheel is at rest. Asshown, the pipe E, is also provided with a laterally directed branch 6,which is connected by means of a hose pipe 6 with a pipe 6 which extendsupwardly into the carrying wheel C, and is provided likewise with branchpipes c-e -c such as before described, the arrangement and constructionof which, and the burners therefor are each as before described withreference to the carrying wheel C. Also extending upwardly at the end ofthe frame is a pipe F, connected with a suitable blower or source of airpressure, said pipe also extending through the adjustable clamp e, andthence upwardly and inwardly of the carrying wheel and be neath theshaft B, and provided, as shown in Fig. 6, with branches j, two innumber, and positioned to direct a cold blast through two adjacentapertures in the plates 0, and next adjacent to those acted upon by theburners. In a similar manner a branch f extends from said pipe F, and isconnected by means of a hose pipe F, with a corresponding pipe f whichextends into the carrying wheel C, and is likewise provided withbranches as before described, and for the same purpose. As shown also,the pipes f and a are secured on the frame bar a, by means of anadjustable clamp e.

Secured at the rear side of the frame is a' chute G, which inclinesinwardly and down wardly to direct released blanks upon the lowerinclined chute g, which is directed rearwardly and downwardly toward anyThe operation is as follows: The carrying wheels are adjusted on theshaft B, by loosening the set screws and sliding the same to a positioncorresponding with the length of the blank it is desired to operateupon, this, of course, depending upon the size of the pail to be made,said adjustment being such that the blanks when laid upon the flat facesof the carrying wheels shall be so positioned that the point at which itis desired to attach the lugs lies centrally over the apertures in theplate 0 Having so adjusted the carrying wheels, the same are rigidlyengaged upon the shaft by means of the set screws 0 and if necessary,the cam rings (Z may be also adjusted by loosening the nuts in the lowerend of the bar (P, and sliding the same to whatever extent may benecessary to insure said bars at all times clearing the clamping levers.Of course, the fuel and air pipes are likewise adjusted to insure thatthe delivery thereof is at the center of the ear lug attached to theblank. For this purpose, the clamps e-e may be adjusted longitudinallyof the frame bar a, to exactly position said pipes as desired. Theflexible hose sections 6 -f permit of any desired adjustment thereof.Having adjusted the machine, the blanks are fed into place beneath theclamping jaw at the station indicated by X, on Fig. l and Fig. L, atwhich point the clamping lever is elevated on the cam D, affording spaceto insert the blank and to drop the ear lug indicated by 00, in place,one near each end of the blank, as shown in Fig. 2. This is accomplishedduring the interval of rest of the carrying wheels. The continuousrotation of the gears, however, almost immediately brings the pin Z),into one of the notches in the Geneva gear, with the effect of rotatingthe carrying wheels another station and closing the clamping jaws uponthe ear lug and blank partly under action of gravity owing to the weightof the clamping levers, but mainly, because of the action of the springd", which forces said lever downwardly bringing the clamping aw firmlyinto clamping relation. The carrying wheels coming to rest at the nextstation position the blank and the ear lug directly in alinement withthe first burner e, heating the blank beneath the ear lug, and (inasmuchas the ear lug before insertion into the machine had been coated on theunder side its flange with solder) fusing the solder, and also the thincoating of tin on the blank. Inasmuch as the interval of rest isexceedingly brief, several of such burners are desirable, though thenumber, of course, will depend upon the rapidity of motion of thecarrying wheels and the length of the period or interval of rest. Inpractice, it has been found that three of such burners permit of rapidmovement of the wheel and very brief intervals of rest, in fact, thebriefest possible interval consistent with the insertion of the blanksand the ear lugs into place manually. Having passed the last burner 0 atwhich the solder was completely fused, at the next interval of rest thehot spot on the blank is positioned directly opposite one of the coldblast branches f, rapidly cooling the same and also cooling the thinplate 0, upon which the blank rests. Such cooling operation may also becontinued for one or more intervals, any desired number of such branchesbeing connected in the cooling pipe. The cooling, however, havingsufficiently progressed to solidify the solder, the depending end of thecam lever next engages the inclined face of the cam D throwing theclamping jaw outwardly, as shown in Fig. 4., and permitting the blank tofall upon the inclined chutes Gg and into the receptacle g.

Owing to the peculiar construction of the flat faces of the carryingwheels the width of the blank is quite immaterial, inasmuch as the edgesof each blank indicated by Y, may project over the clamping jaw for thenext preceding blank, in this manner enabling the machine to receive andto operate successfully upon blanks of any desired width.

Of course, I am aware that instead of ten clamping jaws on each carryingwheel the number of flat faces and corresponding clamping jaws may varydepending upon the size of the wheel, its rate of movement and whetherthe blanks and ear lugs be fed manually into position or automatically,which may, of course, be very easily accomplished. I am also aware thatfor any blank or article which may be more or less curved or present anon-fiat surface, the face of the wheel should desirably be shaped tolit thereto, and of course, the clamping jaws desirably shaped on theunder face to con form somewhat to the article to be engaged upon theblank. Furthermore, the intermittent motion is not indispensable,inasmuch as a. slower rate of continuous rotation per mits of thefeeding of the blanks or the lugs or articles to be attached theretointo position very readily, and when automatically feeding, continuousrotation may be preferable, with, of course, the consequent variation inthe number of burners and cooling nozzles.

Obviously, many features of construction and operation may be varied andI therefore do not purpose limiting this application for patentotherwise than necessitated by the prior art.
